IV. BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a perspective exterior view of a window with the present invention installed.
FIG. 2 shows a perspective interior view of a window with the present invention installed.



V. DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a perspective exterior view of a window 1 with the present invention installed, while FIG. 2 shows a perspective interior view of a window 1 with the present invention installed. The present invention would be an electronic external cleaning system for windows in buildings, preferably skyscrapers, that would comprise a wiper blade 2, a strip of water-dispensing jets 4, a water line 6, a pair of rectangular brackets 8 and 10, a drive chain 11, a control panel 12, a motor 14, a solution reservoir 16, a cap 18, a pump 20, and power means 22 for providing power to the pump 20 and the motor 14.
The wiper blade 2 would act as a squeegee blade and would be the same width as the window and would be horizontally positioned and flush-mounted against the exterior side of the window 1 when installed. The wiper blade 2 would have two ends, a left end and a right end. The window 1 itself would have two sides, an exterior side and an interior side, and the window 1 also has four edges comprising a top edge, a bottom edge, a right side edge, and a left side edge.
The left side edge of the window is mounted into bracket 10, while the right side edge of the window is mounted into bracket 8. Rectangular brackets 8 and 10 would be vertically fitted onto each side of the window frame and would traverse the entire length of the window 1. Each bracket would have two ends, a top end and a bottom end. Each end of the wiper blade 2 would be positioned beneath the two brackets, which would function as guides for the wiper blade 2 during the up and down travel of the blade when the present invention would be used.
One end of the wiper blade 2 would be linked to a drive chain 11 that is propelled by the drive shaft of a small, bi-directional motor 14. The motor 14 would be mounted in the interior space of the window 1, physically attached to one side of the window frame. The drive chain 11 would be looped over a top cog 40 and a bottom cog 42. The top cog 40 is located near the top end of the rectangular bracket 8 within the rectangular bracket 8, while the bottom cog 42 is positioned at the lower corner of the window frame interior and would be axially mounted to the motor. Most of the length of the drive chain 11 is located within the bracket 8.
Positioned just below the motor 14 would be an electrically operated pump 20 which would be connected by a water line 6 to a strip of water-dispensing jets 4 positioned along the top of the window frame. The location of the strip of water-dispensing jets 4 is on the exterior side of the window 1 just above the highest possible position of the wiper blade 2 and would be separate from the wiper blade 2. The water line 6 also is attached to a solution reservoir 16 which would be remotely located several feet from the window within an internal room. A volume of aqueous solution 44 is located within the solution reservoir 16, with this solution being either water or a cleaning solution.
Power means 22 for the motor and pump would preferably be standard household current and would be routed through the control panel 12 which would be positioned on a wall or other desired location in an internal room. The control panel 12 would preferably be a two-position switch, with the two positions being “on” and “of.”
For use, a user would remove cap 18 on solution reservoir 16 and would fill the reservoir 16 with cleaning solution. Then, a user would switch the control panel 12 to the “on” position, allowing the pump to draw cleaning solution from the reservoir 16, through the water line 6, and dispense the cleaning solution through the strip of water-dispensing jets 4 and onto the external side of the window. The motor 14 would continuously propel the wiper blade 2 up and sown over the external side of the length of the window to remote accumulated dust and dirt in a continuous manner until the user was satisfied with the cleanliness of the window. Once satisfied, a user would switch the control panel 12 to the “off” position, allowing the motor and pump operation to cease and allowing the wiper blade 2 to return to the uppermost position against the external side of the window.
